# EXIT

Tags: program control program execution

# Description

The EXIT statement halts the execution of a program and returns a numeric exit code to the parent process.

It takes the general form:

EXIT(expression)

EXIT

where expression must evaluate to a numeric result, which should be the appropriate error code for the environment in which jBASE is being run. The error code is returned to the parent C function exit().

# Note

For compatibility with older versions of the language, the EXIT statement should be used without an expression. In this case, it is synonymous with the BREAK statement.

If the expression does not evaluate to a numeric result the program will enter the debugger and display a suitable error message.

The expression has been forced to be parenthesized to avoid confusion with the EXIT statement without an expression as much as is possible.

Assuming a file has been opened to FileDesc, an example of use is as follows:

    READ Record FROM FileDesc, RecordKey
    ELSE CRT "Record ":RecordKey:" is missing"
        EXIT(1)
    END
